To all whomfz'thmyconcerh: g

Be it known thatI, JOHN A.'VEAZEY, a citizen of the United States,'residing'at Youngstown, in the county of Mahoning and v State of 'Ohio,have invented certain new and useful Improvements in Railway Switches;and I dohereby declare the fol-' lowing to be" a full, clear,- and exactdescription of the invention; such as will enable others skilled in theart to which itappertains to make and use the same.

The invention has relation to railway switches which are locked bothinopen or closed position, thereby preventing accidental movement of theswitch'from either the opener the aclosedposition, and in accord,

ance withthe present invention, the "pri: mary object is to prevent thederailment of a train by running into an open switch,

Other objectsand advantages will be ap parent and suggestthemselve's" asthe nature of the inventio'n'is understood. 1 While thedrawings-illustrate an embodiment of-the invention itis to be understoodthat in adapting the same: to meet different conditions and rrrequirements various changesin the form,- proportion and minordetails-of construction may be resorted'to without departing from thenature of the invention.

Referringzto the Fi 're 1 is atop (plan view of a railway switcembodying the invention; i 5*:

Figure 6 is a sectional detail on the line 66 of Figure 2, showing indotted lines the:1 cut away upper portion of the ties, an

meansbeing providedrwhereby the switch is- Figure 7 is a de tailCorresponding and like parts-are referred to in the followingdescrlption and designated in the several views of the drawings by likereference characters.

The numeral 1 designates. the rails main track and 2 the switch points,the latterv being connected for simultaneous movement by means of a tie3. A box 4 is slidable beneath the main rails land is con nected at oneend'by meansof a link 5 with] a sw1tchstand'6 disposed atone side of thetrack and serving asconvenient means for,

throwing the switch when it is required to operate the same by hand.-The switch point tie 3 has a. twofold slidingmov'ement, the one with thebox 4' and the otherindependently of the box and automatically operableby thetra in. whereby to throw the switch from opento closed position toprevent a casualty. Locking meansv are provided hesection on the line7-7 of Figure 2.

of the tween the switch, point tie 3 and the box 4 to cause both to-mOve,in unison when throwing theswitch by means of the switch stand. Theselocking qmeans consist. of"

similar dogs 7 and .7 and a lock member 8, the latter being disposedwithin the box 4: to move longitudinally therewith and having anindependent vertical movement. :The' dog 7 looks the switchinopenposition and the dog .7 looks the switch in closed position.

Both dogs do' not operate at, the'same'time" andwhen one is in lookingposition, the other is released from-the lock memberg8'.

The lock member. 8 is provided with an-openf ing-e for eachaofthedogs7and-'7? andthe aecomp'anyingdrawings forming a part.:oi.zthe%application:I

switch point tie 3 is: provided with an opening 10-;for eachof: saiddogs; keeper 11 attached to the tie 3 extends overwthe opening '10and,;.confines 'an:--expa nsiblei helical spring 12 normally urgingthegdog 7 01'7 downwaridly whereby to cause it to enter the opening 9when in register "therewith. Expansible helical springs 13' interposedbe-, tween the bottom of the box 4 and the lock member 8 normallysupport the latter in elevated position and. admit of its depressionwhereby to clear the dog 7 to admit of the automatic throwing of theswitch by the train, thereby preventing a casualty from the trainrunning into an open switch. A pin 14. extends upwardly from the bottomof ward movement of the dog so that when the member 8: is depressed,it'clears the, dog, and admits of theswitch points being automaticallymoved by the train. When the switch is automatically thrown by thetrain.from open to closed position, it is locked in the closed position bymeans of the dog 7 To facilitate the vertical movement of the lockmember 8 in the bOX'il, ballbearings:

train and this vertical movement depresses the lock member-8 so as toclear the dogs 7 and'i' thereby releasing-the switch which may beautomatically thrown from open position to closed position-by a flangeof 1 the car wheel engaging aside of: a switch point, andwhen the switchis closed it is automatically-locked. The usual wooden ties 22'at eachside of the tie 3', have portions of their upper surfaces cut away asindicated'at 23 to permit the mainrails 1 to move vertically under theweight of a train, to depress the lock member 8.

'The dog 7 looks at tie 3 to the member Sand as the latter is movablewith box 1 and the latter iscoupled to the switch stand,

it follows that switch may be thrown whenrequiredeither to the open orclosedposi tion by means ofthe stand 6,'the switch being locked ineither position by locking the operating member of the switch stand inany usual "orfpreferred way, I i

The box '4 may be mounted in any preferred way and is directed" in itsmovementsby guides 20 secured to a tie let into the road-bed.Antifriction bearings 21 are interposed betweenthe guides 20' and thebox 1 to reduce the friction tothe smallest amount possible. A lever 19is mounted in aside of' the-box 4 in position to engage a dog 7" or 7120 admit of'either dog being} operated at will independently of thetrain.
